title: Simultaneous occurrence of clinical manifestations of myeloma and Waldenström's macroglobulinemia with monoclonal IgG Lambda and IgM Kappa in a single patient.
abstract: This paper reports a rare case of a patient with biclonal gammopathy IGM kappa and IgG lambda corresponding to the simultaneous occurrence of the clinical manifestations of Waldenström's macroglobulinemia and multiple myeloma. Two cellular populations derived from the B lymphocyte cell line can be observed in this patient. Bone marrow aspiration revealed abnormal plasma cells with inclusions and lymph node aspiration showed immature lymphoid cells containing mu heavy chains.
